Analog Devices Inc. ADM3064E Full-Duplex RS-485 Transceiver
Analog Devices Inc. ADM3064E Full-Duplex RS-485 Transceiver features IEC Electrostatic Discharge (ESD) protection, allowing this device to withstand ±12kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM3064E features a VIO logic supply pin that allows a flexible digital interface to operate as low as 1.62V.
The ADM3064E features a 1/4 unit load input impedance that allows up to 128x transceivers on a bus. This device operates at a low 500kbps data rate and is suitable for operation over long cable runs. A thermal shutdown circuit prevents excessive power dissipation caused by bus contention or output shorting. This feature forces the driver output into a high-impedance state if a significant temperature increase is detected in the internal driver circuitry during fault conditions. The ADM3064E Transceiver guarantees a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled.
